Feel like someone is watching you? If hidden cameras have been installed, they may well be. Knowing how to detect hidden cameras is essential, whether your goal is to prevent unauthorised access to sensitive information or to avoid being followed around. Read on for some tips.

Is anything out of place?

One of the simplest ways to find hidden cameras is to see if anything seems out of place. Start by taking note of any objects that seem out of place or suspicious, such as a clock or a picture frame you don't remember purchasing or one that seems to have been moved to a different location without explanation.

Hidden cameras can also be disguised as other common household items, such as smoke detectors, light fixtures, or even electrical outlets- so it's essential to keep a close eye on these objects as well.

Flashing lights

Hidden cameras are designed to be inconspicuous, making them difficult to detect even in broad daylight. However, many of these cameras are equipped with small LED lights that indicate when they are recording or transmitting data. These lights are typically located near the lens of the camera and can be red, green, or even blue in colour. It is worth noting that some cameras may be equipped with lights that are so small or faint that they are difficult to see with the naked eye.

Suspicious wires may indicate a Hidden Camera

Start by tracing the wire to see where it leads. This may involve following it to a power outlet, a recording device, or another location where the camera may be hidden. However, if you do find one, do not touch or disturb it, as touching or moving the camera could alert the person who installed it and compromise your safety.

Lens glare

Keep an eye out for lens glare, which could indicate the presence of a hidden camera. To detect lens glare, start by looking for shiny or reflective surfaces in your environment. This may include mirrors, picture frames, or even the surface of a desk or table. Take note of any areas where you see a bright, shining spot that seems to be coming from nowhere. Once you have identified a potentially suspicious area, you can try using a flashlight or other light source to see if you can create a lens glare. Shine the light at different angles to see if a bright spot appears, which could indicate the presence of a hidden camera.

Bug Detector

A bug detector is a specialised piece of equipment that reveals the location of undetected surveillance cameras, microphones, and other devices, via the radio signals emitted by these gadgets. They are easy to use; turn on the device and scan the area for any radio signals that are being emitted. The detector will produce an audible or visual alert when it detects a signal, helping you to locate the source of the transmission.

Buzzing sounds

Some hidden cameras can even listen in for signals. Be aware of any unusual buzzing or static sounds that you don't recognise- it could be a microphone. Start by turning off any background noise, and pay attention to areas where people may be likely to speak, such as near telephones, computers, or other communication devices.

Strange signals

If you suspect that there may be hidden cameras in your home or workplace, look for unusual wireless signals or activity. This may include strange Wi-Fi networks or Bluetooth connections that you don't recognise.

Temperature change

Hidden cameras can sometimes cause a noticeable change in temperature. Find any source of heat with a thermal imaging camera; this is a specialised device that is designed to capture and display infrared radiation. It allows you to see the temperature of objects and surfaces in the environment, including any sources of heat that may be associated with a hidden camera.

Smartphone app

Smartphone apps can help you detect hidden cameras. These apps scan the area for anomalous radio signals. These apps use the smartphone's built-in sensors and hardware to scan the environment for anomalous radio signals, similar to how an RF detector works.

Call in experts to detect Hidden Cameras

It may be time to bring in the experts if you're still having trouble finding the hidden cameras. Your home or business can be thoroughly searched by a private investigator or security expert with the help of specialised equipment.
